Figure 1From: Recombinant proteins from Gallibacterium anatis induces partial protection against heterologous challenge in egg-laying hens Lesion scores in immunized or non-immunized birds 48 h after challenge. The columns show the number of birds with a protective response (white bars) or a non-protective response (black bars). Groups were immunized twice with GtxA-N, GtxA-C, FlfA or buffer only (placebo), prior to challenge. Significant differences (P < 0.05) to the control group are marked with *.Back to article page
